Can I get back film emulation looks into 2.80?
Warning: The following approach may currently work, but it's not officially supported and may cause bugs and/or crashes when running Blender.

For this you need a copy of Blender 2.79b which you can download here. Use one of the appropriate one for your OS that comes as archive (.zip, tar.bz2, tar.gz). We will need this to get the old color management files.


Open the directory where you have Blender 2.8 installed and navigate to 2.80/datafiles. There should be a directory named colormanagement. Rename this to colormanagement_new.
Extract Blender 2.79b archive somewhere on your system. Navigate to 2.79/datafiles and copy the colormanagement directory CTRL+C.
The back to the directory of the Blender 2.8 and paste into 2.80/datafiles CTRL+V. You should now see the old options in the color management panel when running Blender 2.8.


If you want to revert the changes simply delete the directory you copied into 2.80/datafiles and rename colormanagement_new back to colormanagement.
